Jeff,
I know alot about the TC's and CVA's because I lived them from their start and owned many models of both, plus started putting together a data base on them both many, many years go. Most of it is buried in storage someplace, but I have some of it on hand. It still has holes in it, new and rare discoveries still come up with the TC sidelocks now and then, but the CVA's are pretty cut and dry. TC was easier for me as I was friends with two top dogs at TC, including the boss from the start over (and a designer of) the smoke poles. With CVA I just knew an old timer there that would feed me what he could, and I owned a bunch of them.
The stock hen scratch referring to 1976 may or may not be from that year (folks do stuff like that to make things appear older. But, your picture helps a lot... not clear enough to be certain on all points, but close. Nothing like having it in hand IOW. It does appear to be a CVA Kentucky. There are "points" to confirm the vintage not clear enough to confirm with the picture, but it appears it could be a combination of 1975/1976 parts. That was standard for them when they transitioned to a newer version of the same model. So it kind of teeters between the 44 cal vintage and the early 45 cal vintage based on what I can see in parts. Barrel length makes it earlier (unless it's been cut down); front sight, thimbles, rod are right for the '76 vintage. The locks varied slightly, so I can't tell if its the early or Maslin lock. When you get it back together measure the over all length of the assembled pistol (that may help as well). New they sold retail for $40-$45 back then depending on who the dealer was.
Best I can offer without going over and finding the data base, and I'm not going to do that. Have fun with it...
